Do not let elements inside display:none subtrees become focus targets.
The HTML focusable-area model only allows elements to be focusable when
they are rendered, delegate rendering to their children, or are relevant
canvas fallback content.
Preserve blur for the current focused area after script hides it, since
the unfocusing steps operate on the old focus target. Check display:none
through the flat-tree style parent chain, so slotted controls inside
hidden slot subtrees cannot become focused.
Cover hidden ancestors with materialized computed style, display:none
controls, display:contents, hidden focused controls, and slotted cases
inside hidden and visible shadow-tree subtrees.
This allows us to use these methods from `SVGAElement` without
inheriting `HTMLHyperlinkElementUtils`, which we can't do for
`SVGAElement` due to a naming conflict with the `href()` method in
`SVGURIReferenceMixin`.
Prevents observably calling Trusted Types, which can run arbitrary JS,
cause crashes due to use of MUST and allow arbitrary JS to modify
internal elements.
- `Threading::Thread` is not polymorphic, there is no need for a virtual
destructor.
- `HTMLAnchorElement::has_download_preference` isn't overridden by
anything.
This warning was introduced in llvm/llvm-project#131188.
Resulting in a massive rename across almost everywhere! Alongside the
namespace change, we now have the following names:
* JS::NonnullGCPtr -> GC::Ref
* JS::GCPtr -> GC::Ptr
* JS::HeapFunction -> GC::Function
* JS::CellImpl -> GC::Cell
* JS::Handle -> GC::Root
We currently have 2 virtual methods to inform DOM::Element subclasses
when an attribute has changed, one of which is spec-compliant. This
patch removes the non-compliant variant.
Now that we have RTTI in userspace, we can do away with all this manual
hackery and use dynamic_cast.
We keep the is<T> and downcast<T> helpers since they still provide good
readability improvements. Note that unlike dynamic_cast<T>, downcast<T>
does not fail in a recoverable way, but will assert if the object being
casted is not a T.
You can now cycle through focusable elements (currently only hyperlinks
are focusable) with the Tab key.
The focus outline is rendered in a new FocusOutline paint phase.
Note that these aren't full implementations of the bindings. This
mostly implements the low hanging fruit (namely, basic reflections)
There are some attributes that should be USVString instead of
DOMString. However, USVString is a slightly different definition
of DOMString, so it should suffice for now.
LibWeb keeps growing and the Web namespace is filling up fast.
Let's put DOM stuff into Web::DOM, just like we already started doing
with SVG stuff in Web::SVG.
